1. Methyl anthranilate, also known as MA, methyl 2-aminobenzoate, or carbomethoxyaniline, is an ester of anthranilic acid. The chemical formula for this compound is C8H9NO2. Methyl anthranilate is a clear to pale yellow liquid with a melting point of 24Â°C and a boiling point of 256Â°.n ester is the product of a reaction between an alcohol and an acid, usually an organic acid.3 Methyl anthranilate is derived from the reaction of methanol and anthranilic acid.
